This week in jewelry, this is the fabulous oura ring that i am holding in my hand. Just a miracle of hardware and censers. It's incredibly light. It's incredibly cheap, or i should say, cheap affordable in price. So why would one wear a smart ring? Well, the ring let you know how your body is doing. And instead of just giving you what my fit bit or your apple watch might get you, the software is designed to give you an idea of your readiness and your restfulness.
